Matthew 12:38-42 - The Sign Of Jonah
38 Then He was accosted by some of the Scribes and of the Pharisees who said, "Teacher, we wish to see a sign given by you."
39 "Wicked and faithless generation!" He replied, "they clamour for a sign, but none shall be given to them except the sign of the Prophet Jonah. 40 For just as Jonah was three days in the sea-monster's belly, so will the Son of Man be three days in the heart of the earth. 41 There will stand up men of Nineveh at the Judgement together with the present generation, and will condemn it; because they repented at the preaching of Jonah, and mark! there is One greater than Jonah here. 42 The Queen of the south will awake at the Judgement together with the present generation, and will condemn it; because she came from the ends of the earth to hear the wisdom of Solomon, and mark! there is One greater than Solomon here.
29 Now when the crowds came thronging upon Him, He proceeded to say, "The present generation is a wicked generation: it requires some sign, but no sign shall be given to it except that of Jonah. 30 For just as Jonah became a sign to the men of Nineveh, so the Son of Man will be a token to the present generation. 31 The Queen of the South will awake at the Judgement together with the men of the present generation, and will condemn them; because she came from the extremity of the earth to hear the wisdom of Solomon; but mark! One greater than Solomon is here. 32 There will stand up men of Nineveh at the Judgement together with the present generation, and will condemn it; because they repented at the preaching of Jonah; and mark! One greater than Jonah is here.
